Changelog

Sourced from fundsp's changelog.

Changes

Version 0.16

• AudioNode now requires Send and Sync.
• Feedback units Feedback64 and Feedback32.
• Shape::Atan was contributed by Serdnad.
• New opcode resynth for frequency domain resynthesis.

Version 0.15

• Snoop node for sharing audio data with a frontend thread.
• Meter smoothing parameters are now timescales specified in seconds.
• Shape::SoftCrush was tweaked.
• New adaptive distortion mode Shape::AdaptiveTanh.
• Oversampling now employs a minimum phase halfband filter.
• Net64Backend and Net32Backend are now called NetBackend64 and NetBackend32.
• Sequencer64Backend and Sequencer32Backend are now called SequencerBackend64 and SequencerBackend32.
• Slot32/64 is a real-time updatable audio unit slot with crossfading between units.
• "Hammond" wavetable, which emphasizes the first three partials.
• Reverb time calculation was tweaked to take into account room size.

Version 0.14

• New math functions sqr_hz and tri_hz for non-bandlimited square and triangle waves.
• Lorenz and Rössler chaotic system oscillators as opcodes lorenz and rossler.
• swap_stereo is now generic reverse, which reverses channel order.
• Resonant two-pole filter by Paul Kellett as bandrez and lowrez.
• Sample-and-hold opcodes hold and hold_hz.
• Fixed inbuilt waveform phases.
• Reduced number of all-pass stages in phaser to 10.
• Sequencer add and add_duration are now push and push_duration.
• Reseting a node and setting its sample rate are now two distinct operations.
• Sequencer can now have a real-time safe backend.

Version 0.13

• Fade curves for Sequencer events. To migrate, use the curve Fade::Smooth.
• Net32/64 now operates on stable node IDs of type NodeId. Other improvements.
• swap opcode is now swap_stereo, to avoid possible conflicts with std::mem::swap.
• New method AudioNode::allocate for preallocating everything.
• Identity function has been renamed from id to identity, to match the standard library.
• Setting system MPSC channels were async by mistake; they are now blocking.
• Net32/64 can now have a real-time safe backend.

Version 0.12

• More settings implemented.
• Signal routing is now an exclusive operation, for practical reasons.
• Granular synthesizer. FunUTD is now a dependency.
